The Law of Similars by Chris Bohjalian

This is riveting medical thriller about a lawyer, a homeopath, and a tragic death.  When one of homeopath Carissa Lake's patients falls into an allergy-induced coma, possibly due to her prescribed remedy, Leland Fowler's office starts investigating the case. 

But Leland is also one of Carissa's patients, and he is beginning to realize that he has fallen in love with her.  As love and legal obligations collide, Leland comes face-to-face with an ethical dilemma of enormous proportions. 
Done in Bohjalian’s typical manner the book is fast-paced and riveting. I love everything of his that I have read.

4 stars (Rated R for brief but explicit sex)
